The determination of Nd, U and Pu by isotope dilution analysis is well
known as the classical method for the calculation of the burn-up of a
nuclear fuel. Numerous isobaric overlaps restrict the direct determin
ation of fission product and actinide isotopes by mass spectrometry an
d therefore an extensive chemical separation is required. As a first s
tep towards the development of a more advanced method for the determin
ation of fission product isotopes in irradiated uranium fuel, high-per
formance liquid chromatographic (HPLC) and inductively coupled plasma
mass spectrometric (ICP-MS) systems were installed in glove-boxes and
all the lanthanides were separated by HPLC and detected on-line by ICP
-MS, As high U and Pu concentrations strongly suppress the signals of
trace elements in ICP-MS, a separation method to elute U and Pu first
was developed. Thus it was possible to determine the isotopic composit
ion of Nd in a high U and Pu matrix. With the same equipment, a method
was developed to prevent isobaric overlaps in the mass spectrum by se
parating U, Am and Pu.
